<p>Registers a new tag type for the use with GStreamer's type system. If a type
with that name is already registered, that one is used.
The old registration may have used a different type however. So don't rely
on your supplied values.</p>
<p>Important: if you do not supply a merge function the implication will be
that there can only be one single value for this tag in a tag list and
any additional values will silently be discarded when being added (unless
<a class="link" href="GstTagList.html#GST-TAG-MERGE-REPLACE:CAPS"><span class="type">GST_TAG_MERGE_REPLACE</span></a>, <a class="link" href="GstTagList.html#GST-TAG-MERGE-REPLACE-ALL:CAPS"><span class="type">GST_TAG_MERGE_REPLACE_ALL</span></a>, or
<a class="link" href="GstTagList.html#GST-TAG-MERGE-PREPEND:CAPS"><span class="type">GST_TAG_MERGE_PREPEND</span></a> is used as merge mode, in which case the new
value will replace the old one in the list).</p>
<p>The merge function will be called from <a class="link" href="GstTagList.html#gst-tag-list-copy-value" title="gst_tag_list_copy_value ()"><code class="function">gst_tag_list_copy_value()</code></a> when
it is required that one or more values for a tag be condensed into
one single value. This may happen from <a class="link" href="GstTagList.html#gst-tag-list-get-string" title="gst_tag_list_get_string ()"><code class="function">gst_tag_list_get_string()</code></a>,
<a class="link" href="GstTagList.html#gst-tag-list-get-int" title="gst_tag_list_get_int ()"><code class="function">gst_tag_list_get_int()</code></a>, <a class="link" href="GstTagList.html#gst-tag-list-get-double" title="gst_tag_list_get_double ()"><code class="function">gst_tag_list_get_double()</code></a> etc. What will happen
exactly in that case depends on how the tag was registered and if a
merge function was supplied and if so which one.</p>
<p>Two default merge functions are provided: <a class="link" href="GstTagList.html#gst-tag-merge-use-first" title="gst_tag_merge_use_first ()"><code class="function">gst_tag_merge_use_first()</code></a> and

</pre>
<p>Returns a writable copy of <em class="parameter"><code>taglist</code></em>
.</p>
<p>If there is only one reference count on <em class="parameter"><code>taglist</code></em>
, the caller must be the
owner, and so this function will return the taglist object unchanged. If on
the other hand there is more than one reference on the object, a new taglist
object will be returned (which will be a copy of <em class="parameter"><code>taglist</code></em>
). The caller's
reference on <em class="parameter"><code>taglist</code></em>
 will be removed, and instead the caller will own a
reference to the returned object.</p>
<p>In short, this function unrefs the taglist in the argument and refs the
taglist that it returns. Don't access the argument after calling this
function. See also: <a class="link" href="GstTagList.html#gst-tag-list-ref" title="gst_tag_list_ref ()"><code class="function">gst_tag_list_ref()</code></a>.</p>
